oh, hrm. It's already doing what I thought was sufficient but it won't
link will it:
+# Check if we have a fallocate libc call (Linux)
+ [ AC_MSG_CHECKING([for fallocate])
+ ], [
+ fallocate(0, 0, 0, 0);
+ ], have_fallocate=yes
Instead of above does this work better?
(just change AC_TRY_COMPILE to AC_TRY_LINK)
[ AC_MSG_CHECKING([for fallocate])
fallocate(0, 0, 0, 0);
